Decentralized Control and Adaptation in Distributed Applications via Web and Semantic Web Technologies

The presented work provides an approach and an implementation for enabling decentralized control in distributed applications composed of heterogeneous components by benefiting from the interoperability provided by the Web stack and relying on semantic technologies for enabling data integration. In particular, the concept of Smart Components enables adaptability at runtime through an adaptation layer and is complemented by a reference architecture as well as a prototypical implementation

Tactics, Techniques and Procedures (TTPs) to Augment Cyber Threat Intelligence (CTI): A Comprehensive Study

Sharing Threat Intelligence is now one of the biggest trends in cyber security industry. Today, no one can deny the necessity for information sharing to fight the cyber battle. The massive production of raw and redundant data coupled with the increasingly innovative attack vectors of the perpetrators demands an ecosystem to scrutinize the information, detect and react to take a defensive stance. Having enough sources for threat intelligence or having too many security tools are the least of our problems. The main challenge lies in threat knowledge management, interoperability between different security tools and then converting these filtered data into actionable items across multiple devices. Large datasets may help filtering the massive information gathering, open standards may somewhat facilitate the interoperability issues, and machine learning may partly aid the learning of malicious traits and features of attack, but how do we coordinate the actionable responses across devices, networks, and other ecosystems to be proactive rather than reactive? This paper presents a study of current threat intelligence landscape (Tactic), information sources, basic Indicators of Compromise (IOCs) (Technique) and STIX and TAXII standard as open source frameworks (Procedure) to augment Cyber Threat Intelligence (CTI) sharing

WeblabSim

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, June 2005.Includes bibliographical references (p. 149-157).In the field of microelectronics, a device simulator is an important engineering tool with tremendous educational value. With a device simulator, a student can examine the characteristics of a microelectronic device described by a particular model. This makes it easier to develop an intuition for the general behavior of that device and examine the impact of particular device parameters on device characteristics. In this thesis, we designed and implemented the MIT Device Simulation WebLab ("WeblabSim"), an online simulator for exploring the behavior of microelectronic devices. WeblabSim makes a device simulator readily available to users on the web anywhere, and at any time. Through a Java applet interface, a user connected to the Internet specifies and submits a simulation to the system. A program performs the simulation on a computer that can be located anywhere else on the Internet. The results are then sent back to the user's applet for graphing and further analysis. The WeblabSim system uses a three-tier design based on the iLab Batched Experiment Architecture. It consists of a client applet that lets users configure simulations, a laboratory server that runs them, and a generic service broker that mediates between the two through SOAP-based web services. We have implemented a graphical client applet, based on the client used by the MIT Microelectronics WebLab.(cont.) Our laboratory server has a distributed, modular design consisting of a data store, several worker servers that run simulations, and a master server that acts as a coordinator. On this system, we have successfully deployed WinSpice, a circuit simulator based on Berkeley Spice3F4. Our initial experiences with WeblabSim indicate that it is feature-complete, reliable and efficient. We are satisfied that it is ready for beta deployment in a classroom setting, which we hope to do in Fall 2004.by Adrian Solis.M.Eng
